'American Idol' Winner David Cook Chops It Up With Green Day Producer

David CookGreen Day, My Chemical Romance, Eric Clapton ... David Cook? That's what Grammy-winning producer Rob Cavallo's résumé will look like soon. The man who helped make American Idiot and The Black Parade modern classics is dipping his toes into the "American Idol" pool, signaling one of two things: Either Cook is the real deal, or, well, a gig's a gig.

A rep for Cook's label, 19 Recordings/ RCA Records, told MTV News that Cavallo — who is currently in the studio with the Dave Matthews Band — has teamed up with the "Idol" winner to work on all of the songs on Cook's debut, which is due this fall.

Cook told EW.com that he thinks Cavallo is "a great producer with the kind of sound that I want. ... And in talking to him, he's just a good guy. Like the song selection I had on the show, Rob just fit."

Working around Cook's schedule on the American Idols Live! Tour, the pair are ducking into studios when time permits. Cook is co-writing the majority of the songs on the album, with professional help from Raine Maida of Our Lady Peace, Chantal Kreviazuk, the Nixons' Zac Maloy and Ed Roland of Collective Soul, among others.
